Point 2. With age
With age, the areas that need filling change
A face that was an inverted triangle in youth becomes closer to a triangle with age. We decide where to fill based on your age and face shape.

Medical note
3cc Face LINE ON in detail
From here, we explain how the surgery works, recovery and what to watch for in more detail. It’s written to the standards Dr. Oh uses when he sees patients.
A note from Dr. Oh
Filling one area of the face on its own looks unnatural. I look at how the forehead, cheeks and chin work together. The aim isn’t to make the face bigger, so if we fill only the areas that need support, 3 mL is enough for most people.Dr. Oh Hae Seok, Medical Director
This may suit you if…
Surgery worries you, recovery time feels like a burden, or you’d rather not have a large amount of filler. It may also suit you if you’ve considered collagen stimulators such as Juvelook or Sculptra but worry about lumps (nodules), or find the repeat sessions too costly.
If your face has little volume or weak structural support, and people have told you your face looks flat or that you look older than your age, 3cc Face LINE ON can help bring back features that have become hidden.
This may not suit you if…
If your face has very little volume, 3 mL may not be quite enough. In that case, you can start with 3 mL and, if you’re happy with the result, add more filler or add facial fat transfer later.
We also don’t recommend it if your face is fuller and reducing volume matters more than adding it. Even so, if areas that need structural support lack volume, treatment may still be an option. We’ll give you a clear answer after examining you.
Procedure, time & anesthesia
We examine and analyze your face, then spend about 5–10 minutes talking through where volume is missing, which areas to fill and your skin elasticity.
The treatment takes 5–10 minutes. You can choose between local anesthesia and IV sedation.
Pain, recovery & returning to daily activities
The anesthetic may hurt a little as it goes in, but the treatment itself usually isn’t very uncomfortable. When the anesthetic wears off later that day, people who are sensitive to pain may feel mild discomfort or a sense that something is under the skin, though most people don’t.
You can return to daily activities the same day. Please avoid alcohol for 1 week after treatment.
Results, how long they last & repeat treatment
You can see the change right after treatment. There may be some mild swelling for 2–3 days.
How long it lasts varies from person to person, but it’s usually about 1–2 years. If needed, a small touch-up can be done after about a month. Touch-ups are charged separately.
A common misconception
Two common worries are that filler will slide down over time, and that it can’t be removed later without being scraped out.
When filler is placed deep and in small amounts where the face needs structural support, it rarely moves. If it ever needs to be removed, it can be dissolved with an enzyme injection (hyaluronidase). Injected accurately, this leaves almost no trace.

3cc Face LINE ON: questions answered by Dr. Oh
3cc 페이스 라인온은 얼마나 유지되나요?
사람마다 차이는 있지만 1~2년 정도로 봅니다. 효과는 시술 직후부터 보이고, 2~3일은 조금 부을 수 있습니다.
What’s the difference between Korean-made and imported fillers?
It’s less about Korean-made versus imported than about the manufacturer. Each company has its own way of producing hyaluronic acid and of treating the cross-linking agent, which affects how much of it remains after the final washing. Each also has its own processes, standards and specifications for the filler’s physical properties.
Why use 3 mL of filler in total instead of treating each area separately?
Because a face is about the balance of the whole, not about individual parts.
How do you decide where to put filler on my face and how much?
Faces vary too much from person to person to fit a single formula. I look at your face to see where structural support is lacking, then set priorities within the fixed amount of filler.
Can filler cause an allergic reaction?
Rarely, yes. Because filler isn’t your own tissue, it can occasionally cause an allergic or hypersensitivity reaction. If that happens, we dissolve the filler with an enzyme injection (hyaluronidase) so your body can absorb it.
Is 3 mL of filler really enough?
For most people, yes. The aim isn’t to add volume and make the face bigger, but to reinforce the areas where the face lacks structural support.

필러 3cc로 정말 충분할까요?

30대와 40대에 채우는 자리가 다른 이유
나이가 들면 얼굴은 역삼각형에서 삼각형으로 바뀝니다. 그래서 꺼져 보이는 곳을 채우기보다, 받쳐 주는 힘이 약해진 곳을 찾아 채웁니다.
히알루론산 필러는 정말 6개월이면 없어질까
히알루론산 필러는 보통 6개월에서 1년 간다고 안내됩니다. 그런데 얼굴 중앙에 필러를 맞은 33명을 MRI로 본 연구에서, 2년 안에 다 사라진 사람은 없었고 길게는 15년 뒤에도 남아 있었습니다.
국산 필러와 수입 필러, 무엇이 다른가요
필러는 국산이냐 수입이냐로 나누기보다 회사별로 보셔야 합니다. 원료와 가교제 처리, 물리적 특성의 기준이 회사마다 다릅니다. 다만 사람 몸에 쓰는 허가를 받으려면 어느 제품이든 안전성은 똑같이 확인받아야 합니다.
